After purchasing Active@ KillDisk a registration key will be emailed to you as well as a download link to installation package named KILLDISK-<VERSION>-SETUP.EXE (Windows versions) , (Linux version) or KillDiskMacOS.dmg (Apple macOS/OS X). This file contains everything you need to get started - just double click the file and installation wizard will take you through the setup process. You need to have Administrator's privileges to be able to install it properly.

Note: If you purchased the Ultimate version you receive installation executable file to run on Windows. To access the Linux installation files install KillDisk on your Windows machine and navigate to the application directory. In Linux sub-folder you will find the Linux installation files. The path to the Linux application will look something like: C:\Program Files\LSoft Technologies\Active@ KillDisk Ultimate\Linux\KillDisk_Linux_Installer.tar.gz

After installation Active@ KillDisk still starts as a FREEWARE (unregistered) version having limited functionality. You need to register it first to have all professional features activated.

The installed package contains two main applications:

  • Active@ KillDisk - Run this application to inspect local disks and erase/wipe your data
  • Active@ Boot Disk Creator - Create a bootable CD/DVD/BD/USB disk to boot from and run KillDisk. Using KillDisk this way allows you to wipe out confidential data from the system volumes while gaining exclusive use to partitions because the operating system runs outside the partition that you are securing.

Windows versions:

In order to install the application double click KILLDISK-<VERSION>-SETUP.EXE file and follow the instructions in the installation wizard.

Linux versions:

In order to install KillDisk make sure you found the Linux installation file as mentioned in the note above. Double click KillDisk_Linux_Installer.tar.gz in your Linux environment and unpack the archive to a proper location.

To start installation simply run the following command in the directory where the archive was unpacked:

sudo ./

KillDisk will be installed to /opt/lsoft/KillDisk/ and menu shortcut will be created.

Apple macOS / OS X versions:

In order to install KillDisk make sure you found the installation file as mentioned in the note above. Double click KillDiskMacOS.dmg and follow installation steps. Drag and drop Active@ KillDisk to Applications folder.

KillDisk will be installed as /Applications/ and KillDisk shortcut appears in Applications in Finder.

Note: Boot Disk Creator and Boot Disks are not supplied for macOS / OS X because newest Apple M1/M2 processors much differ from Intel architecture and do not support Windows-based or Linux-based bootable environments. If purchased commercial version, you can still request Boot Disk Creator for macOS /OS X plus related Boot Disks from us, however prepared bootable media will boot and erase the only legacy Intel-based Macs (not M1/M2).
